So I upgraded my A7V+AthlonXP to a K8V+Athlon64 last week.
I am having some extremely strange problems.
Problem #1:
While a cold boot succeeds, a reboot after a successful boot (whether
initiated in software or using the reset button) results in a
long-short-short beep code which if I recall correctly should be a video
error, and nothing appears on screen. The only way to get it to reboot at
this point is to switch the power supply off and on again. This boot
succeeds. But another subsequent reboot and it's back to a blank screen
with a long-short-short beep code (though HDs seem to be spinning up
successfully). I've tried two different video cards and insured that the
first, a Radeon 9700 Pro, had its PSU connector successfully seated (the
latter, a Geforce 4 4200, requires no PSU power) and both produce identical
results.
Then more weirdness proceeds:
After powering off the PSU and booting, I will receive an "overclocking
failed" error message. I have not overclocked the system and have gone to
great pains to make sure CPU temperature and case temperature are ideal
(this is a very well cooled system). The BIOS reports the CPU as
automatically clocking itself at 1800MHz, which is correct, being an Athlon
64 2800+. I have subsequently tried manually setting the memory clock, with
exactly the same results. Same problems.
I have tried four different DIMMs (paired as well as single) in the
following configurations:
2x512MB DDR400 DIMMs
1x512MB DDR400 DIMMs
2x512MB DDR266 DIMMs
1x512MB DDR266 DIMMs
And no dice. I have also run exhaustive Memtest86 tests on both pairs and
they produce no errors. The DDR 266 pair has functioned perfectly well on
my A7V for the last year. The DDR400 pair is new.
That's Problem #1

Problem #2:
On a successful cold boot, installation of WinXP fails miserably. No matter
what drive it's installing from (I've tried straight from HD as well as from
two different CD drives) or installing to (tried two different HDs), it
can't find many of the files on disk (files which I have verified are there
on the drive on separate boots and perfectly readable on another computer)
and fails to install successfully.
The weird thing is, it always can't find the SAME files, the first of which
is tahoma.ttf, even though they're on a hard drive and accessible or on an
equally accessible CD, and no matter which drive they're installing from. I
can conceive of no rational explanation for how this can be. I think I'm
living in an alternate universe.
That's Problem #2.
Sheesh.
Any thoughts?
